A dedicated circuit serves only one appliance — no other outlets or devices share it. NEC and appliance manufacturers require dedicated circuits for: refrigerators (15–20A), dishwashers (20A), microwaves over 1,200W (20A), electric ranges (50A 240V), electric dryers (30A 240V), HVAC equipment (per nameplate), water heaters, garbage disposals, and EV chargers. Home offices and home theaters also benefit from dedicated circuits to prevent tripped breakers and interference. RainFire Builders designs the circuit plan to include all required and recommended dedicated circuits before rough-in begins — not as an afterthought when an appliance doesn’t work at move-in.
